Subject: [PATCH v3 0/2] [gdb] untie and validate inheritance location
Date: Thu, 30 Sep 2021 16:26:45 -0300 [thread overview]
Message-ID: <20210930192647.31897-1-blarsen@redhat.com> (raw)
This started with what was thought of as an incorrect inheritance
location expression, but turned out to be a correct, but unusual
expression, and uncovered an incorrect assumption when calculating
offsets of baseclasses.
This patchset is the new iteration of that solution, that changed
gnuv3_baseclass_offset calculation to allow for non-virtual inheritance
that has a non-trivial location expression and also moved the basic
validation to this function. The check in value_contents_copy_raw was
changed to an assert.
Finally, the test was expanded to have one incorrect trivial location,
and two non-trivial location expressions, one correct and one incorrect.
